Abstract: A method of mounting cars on a free standing space elevator tower. The actively stabilized space elevator tower has a segmented elevator core structure, each segment being formed of at least one pneumatically pressurized cell. The method of mounting the elevator cars allows the cars to ascend or descend on the outer surface of the elevator core structure or in a shaft on the interior of the elevator core structure. The elevator cars grip the structure without use of a track and are able to pass other cars enabling bi-directional traffic flow using a twisting motion. The freestanding tower can be used for launch activities, tourism, observation, wind-energy generation, scientific research, and communications.

Abstract: A method for the high-speed, high-accuracy approximation of spectrally integrated line profiles is described. The approach enables the computation of line-by-line (LBL) radiative transfer at reduced spectral resolution without loss of accuracy. The algorithm provides rapid and accurate computation of area under the line function in a way that preserves spectral radiance and, consequently, radiant intensity. The error analysis we provide shows the high-accuracy of the approximations presented. A comparison of the performance of the method with that of the traditional LBL approaches is given.

Abstract: A method of constructing an elevator core structure for a space elevator tower. The actively stabilized space elevator tower is a pneumatically pressurized structure formed from flexible sheet material. This construction method comprises raising a core segment with a climbing construction elevator that grips the outer surface of the core structure, sliding the core segment on top of the core structure on a horizontal track, and actively adjusting the core structure's center of mass. The freestanding tower can be used for launch activities, tourism, observation, energy generation, scientific research, and communications.

Abstract: A method of constructing an elevator core structure for a space elevator tower. The actively stabilized space elevator tower is a pneumatically pressurized structure formed from flexible sheet material. This construction method comprises extruding core segments from a liquid core material. Pods containing control and stabilization machinery are embedded in the core segments as they are extruded, and raised. Fiber can be embedded in the elevator core structure to increase elasticity. There are also options to provide the control and stabilization machinery on a base, and to raise the pods with a roller system and pneumatics. The freestanding tower can be used for launch activities, tourism, observation, energy generation, scientific research, and communications.

Abstract: A freestanding space elevator tower for launching payloads, tourism, observation, scientific research and communications. The space elevator tower has a segmented elevator core structure, each segment being formed of at least one pneumatically pressurized cell. The pressure cells may be filled with air or another gas. Elevator cars may ascend or descend on the outer surface of the elevator core structure or in a shaft on the interior of the elevator core structure. A payload may be launched from a pod or deck at the upper end of the space elevator tower. The space elevator tower is stabilized by gyroscopic and active control machinery. The space elevator tower maintains a desired pressure level through gas compressor machinery. Methods of constructing the space elevator are also disclosed.
